COVID vaccine by year-end will be fastest pace for novel pathogen in history: White House

"We do expect to have a vaccine by the end of the year. That has always been the goal and we are still on track for that," White House Press Secretary Kayleigh McEnany told reporters at a news conference here.

A vaccine for COVID-19 by the end of the year will be the fastest pace for a novel pathogen in history, the White House said on Thursday, asserting that it has been the goal of the administration and it is still on track for that.

"We do expect to have a vaccine by the end of the year. That has always been the goal and we are still on track for that," White House Press Secretary Kayleigh McEnany told reporters at a news conference here.

It is very important what US President Donald Trump has done with regard to commercial-level manufacturing, she said.

"The fact that you have scaled up to manufacture these vaccines in advance is something that this president has done, as he is a businessman and thinks through exactly how to get a safe and effective vaccine delivered at a record speed. And part of that has entailed manufacturing in advance," McEnany said.

How does a vaccine work?

A vaccine works by mimicking a natural infection. A vaccine not only induces immune response to protect people from any future COVID-19 infection, but also helps quickly build herd immunity to put an end to the pandemic. Herd immunity occurs when a sufficient percentage of a population becomes immune to a disease, making the spread of disease from person to person unlikely. The good news is that SARS-CoV-2 virus has been fairly stable, which increases the viability of a vaccine.

How many types of vaccines are there?

There are broadly four types of vaccine — one, a vaccine based on the whole virus (this could be either inactivated, or an attenuated [weakened] virus vaccine); two, a non-replicating viral vector vaccine that uses a benign virus as vector that carries the antigen of SARS-CoV; three, nucleic-acid vaccines that have genetic material like DNA and RNA of antigens like spike protein given to a person, helping human cells decode genetic material and produce the vaccine; and four, protein subunit vaccine wherein the recombinant proteins of SARS-COV-2 along with an adjuvant (booster) is given as a vaccine.

What does it take to develop a vaccine of this kind?

Vaccine development is a long, complex process. Unlike drugs that are given to people with a diseased, vaccines are given to healthy people and also vulnerable sections such as children, pregnant women and the elderly. So rigorous tests are compulsory. History says that the fastest time it took to develop a vaccine is five years, but it usually takes double or sometimes triple that time.

"To do this, it normally takes years to scale up to commercial-level production. But this president has done it in just a few short months. If we have this vaccine by the end of the year, it will be the fastest pace for a vaccine for a novel pathogen in history," she added.

In response to another question on the president's suggestion a day before that he might overrule stricter standards at the FDA on the coronavirus vaccine, McEnany said the Food and Drug Administration does have strict standards.

"They are the gold standard with regard to vaccines. The president was referring to the normal interagency process that happens with guidance and that includes running through the office of management and budget, so that is standard operating procedure," she said.

In a separate statement, Al Mason, co-chair of the Trump Victory Indian American Finance Committee, praised the president for his successful fight against the coronavirus.

"President Trump has done an extraordinary job, fighting the made in China virus on all fronts every single day," he said.
